Abstract:
An engine control system comprises an oxygen comparison module and a regeneration control module. The oxygen comparison module compares an oxygen concentration of an exhaust gas of an engine to an oxygen threshold. A regeneration control module initiates regeneration of a particulate filter and controls regeneration based on the oxygen comparison and at least one of a particulate filter load, a particulate filter temperature, and a speed of the engine.
